Question

我想拥有相同的XAML，但是在C＃代码中：

<Application.Resources>

    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Light">
                <SolidColorBrush x:Key="SystemControlHighlightBaseMediumLowBrush" Color="White" />
                <SolidColorBrush x:Key="SystemControlHighlightBaseHighBrush" Color="White" />
            </ResourceDictionary>
        </ResourceDictionary.ThemeDictionaries>

    </ResourceDictionary>

</Application.Resources>

Answer 1

将以下内容添加到您的应用OnLaunched方法：

ResourceDictionary lightTheme = new ResourceDictionary();
lightTheme["SystemControlHighlightBaseMediumLowBrush"] = new SolidColorBrush(Windows.UI.Colors.White);
lightTheme["SystemControlHighlightBaseHighBrush"] = new SolidColorBrush(Windows.UI.Colors.White);
App.Current.Resources.ThemeDictionaries.Add("Light", lightTheme);

Answer 2

您可以使用

Brush SystemControlHighlightBaseHighBrush = new SolidColorBrush(Colors.White);
Brush SystemControlHighlightBaseHighBrush = new SolidColorBrush(Colors.White);

然后您可以像这样使用它来设置按钮的颜色

myButton.Background = SystemControlHighlightBaseHighBrush;

如果您的评论建议您想要更改鼠标悬停时的颜色，则需要捕获鼠标悬停事件，然后您可以将颜色更改为其中一个命名样式。例如，要在鼠标悬停时更改按钮颜色，您可以执行此操作

private void myButton_MouseHover(object sender, System.EventArgs e) 
{
    myButton.Background = SystemControlHighlightBaseHighBrush;
}
